Siemens | NGB1B080L | Circuit Breaker | 80A | 1-Pole | 347V

Siemens NGB1B080L: a purpose-built circuit breaker for demanding 347V commercial and industrial distributions. This 80A, 1-pole unit is designed for maintenance, retrofit, and replacement projects where precise specifications matter and downtime matters. Key specifications you can rely on

• Amperage: 80A
• Poles: 1-Pole
• Voltage rating: 347V
• Part number reference: NGB1B080L is the best reference for compatibility

Why this breaker stands out

The Siemens NGB1B080L isn’t a generic drop-in. It’s a genuine Siemens protection device engineered to perform reliably in 347V distribution environments, helping to guard single-conductor circuits from overloads while aligning with Siemens’ engineering standards. Its single-pole design is ideal for protecting individual legs in commercial or industrial panels where 347V service is used, providing predictable protection for equipment and wiring without unnecessary trips during normal operation.

Ideal use cases

• Maintenance and servicing in panels that require an 80A, 1-Pole breaker rated at 347V
• Retrofit projects where existing equipment calls for the NGB1B080L specification
• Replacement scenarios to minimize downtime and maintain system protection integrity
• Spare part readiness for busy commercial/industrial maintenance teams

Important fit and installation notes

Before ordering, confirm the breaker will fit your panel and carry the correct 347V rating for your distribution. The NGB1B080L part number is the most reliable reference for compatibility, so verify panel labeling and manufacturer's guidelines to ensure seamless replacement.

Practical tips for lasting protection

• Cross-check the panel label to ensure 1-pole, 347V circuits are supported in your enclosure
• Keep a correctly rated replacement on hand to reduce downtime during routine maintenance
• Ensure proper torque and secure connections during installation to maintain reliable operation
